It is important that you only take the "high" bits off. I would suggest you put something hard behind the sandpaper. Personally I would have used a small Arkansas stone for the job (as used by gunsmiths), being very careful to only touch the high bits. If you take your thumb as backing and start scouring away you are going to do more damage than good. Take your time and get rid of the kids, wife, dogs whatever before you start. Careful A small piece of plate glass might be useful to help you feel/see where high spots are. Retrorider2009-01-27 14:19:21

The only version of events available is Stewart's. From his website: "Results Barberton MTN marathon series // 2009-01-241. Max Knox 5-002. Jac jansen Van rensburg 5-01 3. Brandon Stewart 5-05 4. Kevin Evans 7-00 5. David George 8-00" I hope his version of what happened during the race is not as skewed as his version of the results. Wasn't he disqualified? Regarding his version on the web: Wel; today was an awesome day for our team... Max won, Jacque was 2nd and I was 3rd.. So it was a clean sweep which is so good for the first race of the season.. But there was a little drama out on route.. With myself and the king KE.. Kevin. After 80kms Max attacked and Kevin had to chase.. As I was speeding up to get on Kevins wheel.. He just turned into me and switch me right into the bush but lucky I didnt go down.. i saw red and as far as I was concerned he was not going to get away with it that easily... So retaliated with the same treatment... I switched him back but he was so tired that he could hardly hang onto the bars so a little nudge had him eating some dust.. We then waited for him had some words and the racing resumed.. But at the finish Kevin had to have an excuse as he cant take been beaten.. There is always a long story when he doesnt win he can never give any rider credit when they do well.. He then protested and I was DQ because I did not protest first.. Which is so wendy... Its the sport of racing and if you want to play then play but if you come off second best then dont cry about it.. Every rider has there day.. Its the first time in the sport of Mountain biking that there has been a protest.. WHICH SAYS ALOT... I am somewhat skeptical of his version. Sounds to me he was still behind Kevin when Kevin might have changed lanes or something . He has to give a good reason after all as to why he did what he himself did. As to the level of his own response there is no doubt. I also do not appreciate his personal attack on Kevin always having excuses and such. It is about as lame as being South Africa's XC champion after Burry was faster in every race. Retrorider2009-01-25 10:41:28

Farmers get difficult claiming that their animals eat the gel sachets, leading to veterinary problems. This leads to farmers/ nature conservation guys not wanting races to cross their land after previous problems. One possibility I have heard mentioned by a race organizer is to have all sachets and wrappers carried by riders marked with their race number. Spot checks to be done at the start to see that everything marked. If any rubbish is collected along the way bearing your number, it is put up to "name and shame"or for time penalties/ disqualification. Do not know if it would be practical though. Cyclists need to realize though that if they don't put the sticky thingy back in their pocket, next year's race might not happen. This is a serious problem. Retrorider2008-11-18 10:11:02

Why settle for 35mm, perhaps 60mm or even more will give you even better inertia! Perhaps you should experiment in that direction. Or do do you consider Shimano's hubs to have the optimal amount of take up? It's just good marketing Retrorider2008-11-15 16:46:53

When riding singletrack it is nice though if your hub engages "quicker" (Less degrees movement before it engages) Perhaps you can tell us why this is so nice and where it will come in useful. Finally' date=' you're missing my point. I know you claim to do all your ridesin very eroded singletrack where you cranks cannot make full revolutions due to the pedals hitting the embankments on both sides and therefore need a 360/72 degree ratcheting functionality. However, most of us don't do that. We don't continue to erode dongas by attempting to ride them and we don't ratchet our way through rides. We pedal in full circles. Therefore, a pedalling engagement of 360/16 times per revolution is good enough for us. On a 175mm crank, that is a few millimeters of travel. Therefore anything more is a waste. Capish? No, I didn't think so. [/quote'] "We" do not claim to do all our rides in very eroded singletrack. We do not ratchet our way through the forest and we also tend to pedal in circles. If I am correct assuming a typical Shimano freewheel engages after 10 degrees, it gives up to 35mm free play at the end of a 175mm crank. When riding single track one often has to stop pedaling for various reasons. (After a log jump, sharp turn, letting a stump pass under one pedal for example.) When one then start pedaling again it is very "nice" getting immediate lockup. (Not imperative or particularly usefull, but nice) In single track you gain stability from your pedals and it is nice to have what feels like immediate lockup- in other words a more consistant action. I used to ride a wheel with a quick lockup and then went back to Shimano hubs. I did miss the quick lockup till I got used to taking up the slack again, but the less the takeup (or call it slack) the nicer. Perhaps you can tell us why this is so nice and where it will come in useful Maw Johan dit voel lekkerder man.

Depends on the design of the hub , but having more pawls or in some cases sets of pawls that engages is one of the mechanisms used to reduce the degrees movement before engagement. The time it takes to engage is not about the pawl moving inwards towards the centre as I guess you are picturing it, it is about how far the freewheel moves (turns) in comparison with the hub before the next pawl or set of pawls engages. For example it can be done in the following way: "The Industry Nine drive mechanism is a fairly simple, tried-and-true pawl arrangement. When engaged, each of the three driving pawls itself has three points, providing nine points of contact to the hardened A2 drive ring. The drive ring has 60 teeth, which would normally allow a 6-degree engagement ? among the fastest in the industry. Industry Nine proprietary mechanism allows for a second set of three pawls, phased three degrees from the first. This feature cuts engagement time in half, to a mind-blowing three degrees! Their lightning quick take-up has become highly desirable on singlespeeds, twenty-niners, and disciplines with gate starts. " Retrorider2008-11-15 06:14:42

That is not how I remember it. What do you base this on?

"The introduction of disc brakeshas caused increased vulnerability of the front axle and skewer, due to the disc brake applying an ejection force that tends to pull the axle out of the fork. See James Annan's article on disk brake wheel ejection. " (Sheldon Brown) http://www.ne.jp/asahi/julesandjames/home/disk_and_quick_release/index.html Very interesting article. Do not remove the tabs if you intent using disc brakes. Johan was wrong on this one.

Two possibilities: Either this is about taxes/ unpaid duties or some intimidating lawyer instructed by his client managed to convince an inexperienced policeman that they are seizing counterfeit goods If it is the second I would very much like to see the docket and the complainant's statement. That might make good reading. Retrorider2008-10-16 13:16:17
